Discover the Unique Appeal of Hakone Onsen Black Egg Soap

Experience the Magic of Owakudani
with Hakone Onsen Black Egg Soap

When it comes to Hakone, one of the most popular souvenirs is the “black egg” from Owakudani. While these eggs are delicious and renowned for their unique preparation, today we introduce you to a different kind of black egg that you can’t eat but will still leave you delighted: the Hakone Onsen Black Egg Soap.

The Enchanting Owakudani:
Home of the Black Eggs

Owakudani, an active volcanic valley in the famous Hakone region west of Tokyo, is known to locals as “Jigokudani” or the Valley of Hell. This area is famous for its black eggs, which are boiled in sulfurous waters, giving their shells a distinctive black color. The sight of steam rising from vents all around the valley and the smell of sulfur in the air remind you that you’re in an active volcanic area. On clear days, you can also enjoy stunning views of nearby Mt. Fuji.

Introducing the Hakone Onsen Black Egg Soap

Unfortunately, the delicious black eggs from Owakudani have a short shelf life and can’t be shipped overseas. However, we have a wonderful alternative to share with you: the Hakone Onsen Black Egg Soap.

Key Features of Hakone Onsen Black Egg Soap

Superior Moisturizing with Lipidure

This soap contains Lipidure, a moisturizing ingredient twice as effective as hyaluronic acid. Lipidure closely resembles human cell membranes, making it highly compatible with skin and very gentle. This ingredient is so mild and moisturizing that it’s even used in contact lens solutions.

Natural Hot Spring Water

The soap is infused with natural hot spring water, known for its gentle and soothing properties. This “beauty water” is famed for its ability to hydrate and smooth the skin, making it a favorite among women.

Beneficial Ingredients for Skin Health

This soap not only cleanses but also hydrates and nourishes the skin. It includes Lipidure for moisture, EM protein (egg membrane) for elasticity and shine, and hot spring water from Hakone for overall skin health. It’s suitable for use on both the face and body.

Activated Charcoal

The soap contains activated charcoal, which helps to absorb impurities, remove dead skin cells, and detoxify the skin.

Rave Reviews from Happy Users

Review from User A:
“The soap looks exactly like a black egg. It’s amazing! The lather is incredibly rich, and it forms dense, fluffy bubbles when used with a net. Plus, it doesn’t dissolve quickly like other soaps. The most important part, the after-wash feel, is superb. My skin feels smooth and not tight at all. After a week of use, my blackheads started to diminish. It’s fantastic!”

Review from User B:
“This soap is black and firm. It creates fine, fluffy bubbles that leave my skin feeling refreshed and clean. I highly recommend it!”

Review from User C:
“For oily skin or skin that lacks turnover, this soap is perfect. It’s the first time my skin has felt this smooth after washing. I used to use a different soap, but I’ve switched to this one.”
